Abstract
The invention is directed to a probe-type imaging device useful to visualize interior surfaces, e.g., the lumen of blood vessels. Specifically, the probe-type device is particularly useful for direct tissue imaging in the presence or absence of molecular imaging agents.
Claims66
An intravascular imaging device comprising:
- a probe having a body portion;
- a passageway in the body portion through which a guide wire can be extended to transmit light for subsequent directed emission from the probe to a tissue surface;
- and
- a detector assembly on the body portion of the probe for detecting light scattered and reflected from the tissue surface, so that image signals from the detected light can be generated for display in real time.

An intravascular imaging device comprising:
- a probe having a body portion;
- a passageway in the body portion through which a guide wire can be extended for guiding movement of the probe;
- a light source on the body portion of the probe for directed emission of light to a tissue surface;
- and
- a detector array proximal to the light source for detecting light scattered and reflected from the tissue surface, so that image signals from the detected light can be generated for display in real time.
2 more elements
A method for intravascular imaging, the method comprising:
- placing adjacent a tissue surface an imaging device having a probe portion, a mechanism for directed emission of light to a tissue surface, and a detector assembly on the probe portion for detecting light scattered and reflected from the tissue surface;
- activating the device for directed emission of light to the tissue surface;
- advancing the device along the tissue surface;
- detecting light scattered and reflected from the tissue surface;
- and
- generating, in real time, an image of the tissue surface from the detected light for display.
3 more elements
A method for intravascular imaging, the method comprising:
- targeting a tissue area to be imaged with a medium of a contrasting agent;
- placing adjacent the tissue area an imaging device having a probe portion, a mechanism for directed emission, to surrounding tissue, light within a spectrum of wavelengths capable of exciting the contrasting agent, and a detector assembly on the probe portion for detecting light scattered and reflected from the contrasting agent in the surrounding tissue;
- activating the device for directed emission of light to the surrounding tissue;
- advancing the device along the surrounding tissue;
- detecting light scattered and reflected from the contrasting agent in the surrounding tissue;
- and
- generating, in real time, an image of the surrounding tissue from the detected light for display.
